Nikon announce the D4: with video features you always wanted in a DSLR

DSLR News Shooter

In terms of video the D4 can shoot full 1080p or 720p at 29.97, 25 and 24.98 frames a second (fps). It can also shoot standard def 640×480 at 30 or 25 fps. Interestingly, according to Dpreview, it crops the output of the video in FX full frame mode to 91% of its sensor width (I’m not sure why Nikon have done this and I’m trying to find out). Rolling shutter and skew is said to be improved over previous Nikons.
